Title: Improvements in or relating to electric protective arrangements
IPC: H02H3/30
Filed: 1940-07-01
Abstract: 542,287. Protective cut-out systems. REYROLLE & CO., Ltd., A., and COATES, R. H. July 1, 1940, No. 11072. [Class 38 (v)] A section or unit comprising a feeder A<SP>1</SP> ... A' directly connected to a star-constructed transformer (or other power) winding, is protected by balancing the output of current transformers C' ... C<SP>3</SP>   in the three phases at the end remote from the winding, against that of current transformers D<SP>1</SP>, D<SP>2</SP> in two of the phases adjacent the winding and of a transformer E in the earthconnection of the winding, the former transformers being star-connected in the usual way to the primary G of a saturable summation transformer, whereas the star point of transformers D<SP>1</SP>, D<SP>2</SP> is connected to the tapping H<SP>2</SP> of the primary H and transformer E between that tapping and the end H' of the transformer at that end. The secondaries G<SP>5</SP>, H<SP>5</SP> are inter-connected by a pilot circuit J including tuned relay transformers K supplying the operating coils of relays L, the restraining coils L<SP>1</SP> of which are energized by further secondaries G<SP>6</SP>, H'. The arrangement provides full protection for the feeder and earth-fault protection for the winding, but is stable against external earth or phase faults. For example, with an earth fault on A<SP>3</SP> equal parts of the transformers G. H are energized by C<SP>3</SP> and E, respectively, and balance is obtained, whereas with an external fault on A<SP>1</SP>, the whole of both primaries are energized by C<SP>1</SP> at one end and D', E at the other end and adequate balance is obtained in spite of the unequal burdens on the current transformers at the respective ends.

Title: Improvements in or relating to colloid materials
IPC: G03C1/053
Filed: 1946-04-12
Abstract: Photographic gels are produced by treating a polymeric hydroxyalkane containing recurring-CH2-CH(OH)-units in the molecule with an acylacetarylamide.  The polymeric hydroxyalkane may be polyvinyl alcohol, partially and completely hydrolysed polyvinyl esters such as the acetate, chloracetate, and their interpolymers with unsaturated compounds such as vinyl chloride, styrene, acrylic acid esters, and mono-olefines such as ethylene, or a polyvinyl acetal.  Low quantities of acylacetarylamide give thermo-reversible gels and higher quantities give irreversible gels.  The acylacetarylamide may also be used as a colour coupler.  The acylacetarylamide or aqueous solution thereof may be added to a solution or dispersion of the polymeric hydroxyalkane, and the mixture coated, or preformed layers of polymeric hydroxyalkane may be treated with an aqueous solution of acylacetarylamide.  In example 1, an ammoniacal silver nitrate solution containing sodium dodecylsulphate and a solution of ammonium bromide, potassium iodide, and sodium dodecylsulphate are simultaneously added to an aqueous alcohol solution of completely hydrolysed ethylene-vinyl acetate interpolymer, the temperature being held at 45 DEG  C. during precipitation and for 15-60 minutes thereafter, the emulsion is coagulated by addition of acetone and is washed, is dissolved in alcohol, and a further quantity of aqueous alcohol solution of completely hydrolysed ethylene-vinyl acetate interpolymer is added, and the emulsion is coated on baryta-coated paper.  The wet emulsion is over-coated with an aqueous ethyl alcohol-caustic soda solution of N-furoylacet-N1-benzoylacetbenzilide.  In example 2, the wet emulsion is overcoated with an aqueous alcohol solution of acetoacetanilide. In example 3, the procedure is similar, but the binder used is the polyvinyl acetal of N-(m-formylphenyl)-1-acetoxy-2-naphthalenesulphonamide, and the wet emulsion is overcoated with a composition comprising gelatin, N-furoylacet-N1-benzoylacetbenzidide, NaOH, ethyl alcohol, and water. The latter composition may be applied first to the base and the emulsion overcoated thereon.  The acylacetarylamide may also be incorporated in a subbing solution comprising gelatin, a natural or synthetic resin, and a phenol in water, aqueous alcohol, or acidsolvent mixture.  Additional acylacetarylamides specified are benzoylacet-a - or -b -naphthalide, furoylbenzoylacetbenzidide, acetoacet-2 : 5-dichloranilide, acetoacet-m-nitranilide, acetoacetp-anisidide, acetoacet-p-aminoanilide, p-phenylazoacetoacetanilide, acetonedicarboxyanilide, N - benzoylacet - p - phenetidine, and N : N1-dibenzylacetbenzidide.

Title: Improvements in or relating to track engaging brake shoe mechanism for vehicles
Inventor: KNIGHT ROBERT COLIN
IPC: B61H7/02
Filed: 1953-04-24
Abstract: 732,740. Track brakes. SHEEPBRIDGE EQUIPMENT, Ltd. April 26, 1954 [April 24, 1953], No. 11463/53. Class 103 (1). A brake system for trains of rail vehicles, particularly mine trucks, comprises on each car of the train a longitudinal slidable control bar 26 which is urged rearwardly by a compression spring 27 but is prevented from so moving by a latch member 24 pivoted at 22 and engaging a notch 25 in the bar. On one of the cars of the train there is provided on the wheel axle a clutch drum 27 which is engaged by centrifugally operated shoes if the car's speed should become excessive. A lug 20 on the drum 27 is thus caused' to move a lever arm 21 so that the latch member 24 is raised. The bar 26 under the influence of spring 27 thus moves towards the right pivoting, by engagement with a pin 65 an arm 53 so that the hooked extremity of a lever 44 is disengaged from a locking bar 46. Lever arms 39 are thus pivoted about a pin 31 by expansion of compression springs 43 at their upper ends so that the brake shoes 34 at the lower ends engage the rails. The disposition of arms 39 together with parallel links 33 is such that the engagement of the shoe with the rail causes the vehicle to lift and a stop surface 38 to engage the wheel, thus providing effective braking. Movement of the bar 26 on one truck may be communicated by a connecting chain 7 to cause a similar application of the brakes on further trucks in a train. The brake may also be applied manually by a hand lever 70, 71, which through a link 68 having a slotted connection with pin 66 on arm 21, acts also to disengage the latch 24. To reset the mechanism the car is rolled rearwardly to remove the wheels from the stop surface 38, and the bar 26 moved forwardly against the action of springs 27 by a transverse hand lever (not shown).

Title: Improvements in and relating to containers
IPC: A24F15/00
Filed: 1947-04-30
Abstract: 623,325. Time locks. ROBINS, E. T. April 30, 1947, No. 11518. [Class 44] [Also in Groups XVII and XVIII] A container, such as a cigarette case has timing means associated with the lock whereby it is automatically locked when closed, remains locked for a variable set period and is @ automatically unlocked ready to be opened. The case is fastened by a pivoted hook-type catch 19 which is adapted to be released by pressing on the winding head 23 of a watch 15, Fig. 5. Axial movement of the winding spindle 22 is prevented when the case is locked by a lever 30, the other end of which cooperates with a spring- loaded locking finger 32 displaceable by the timing mechanism. The spring barrel 37 of the watch is adapted to drive a pinion 43 which is connected by a light spring friction clutch to another pinion 42 meshing with a setting gear wheel 48. The wheel 48 has a stop 71 adapted to displace the locking finger 32 from 'the locking position against the stop 73 to the unlocking position against the stop 34 after which the clutch on the pinion 42 slips. The setting gear wheel 48 is automatically set at the correct angle from the zero position (shown in Fig. 5) by a projection 27 on a sliding rod 26 adapted to move along the slot 28 when the lid is opened or closed. In its movement, the projection 27 engages a spring ratchet lever 64 mounted on a rotatable setting plate 50 which is thereby turned to engage the stop 34. The plate is connected by epicyclic gears to rotate the setting gear wheel 48 and the angle of this rotation depends on the initial angular displacement of the setting plate 50 which is set by a timing member 58, Fig. 3, mounted on a disc 54 connected to the setting plate 50. The watch face is visible from the front of the case and the period to pass before the lock opens is indicated by figures on the setting gear wheel 48 which are visible through a window 61, Fig. 5, in the watch dial. The winding head 23 is, as usual, pulled out to set the watch hands. That half of the case including the watch mechanism may also include a cigarette lighter.

Abstract: 812,312. Electromechanical filters &c. STANDARD TELEPHONES & CABLES Ltd. April 10, 1957, No. 11671/57. Class 40 (8). The magnetostrictive core element 14 of an electromechanical transducer comprises a pile of equal discs secured together, e.g. by glue, to make a composite cylinder, the total number of discs in the pile being odd and at least some of them being of magnetostrictive material polarized coaxially, e.g. so that the magnetic flux lines are circles coaxial with the disc. Where all the discs are of magnetostrictive material, alternate ones are coaxially polarized. in opposite senses. Alternatively, the oddnumbered discs may be made of magnetostrictive material polarized in the same sense and the even-numbered discs of non-magnetostrictive material, e.g. lead glass. In this case the magnetostrictive material may be a nickel ferrite having a negative temperature coefficient of mechanical resonance frequency which compensates the positive coefficient of the lead glass. The core is surrounded by a driving solenoid 16 and vibrates at the nth harmonic of the fundamental torsional mode where n is the number of discs and the thickness of each disc is equal to half a wavelength at the frequency of the driving current. The core may be connected to the elements of a mechanical filter by a rod 18. Coaxial polarization may be effected by means of a temporary conductor passed through a central hole in the core.
